/install vx-usage
Description
Teaches AI agents how to use vx, the universal dev tool manager. Use when the project has vx.toml or .vx/, or when the user mentions vx, tool version managem...
Usage Guidance
This skill is a documentation-only guide for using vx. Before using it, ensure you trust the vx tool itself (not the skill): vx will auto-download and install developer tools when you run vx commands and can inject environment variables into subprocesses, which can affect tool discovery and behavior. If you plan to let an agent run vx commands autonomously, run them in an isolated environment (container or VM) and avoid giving secrets or system-level credentials to commands the agent may invoke. If you don't have vx installed, verify its official distribution source before installing.
Capability Analysis
Type: OpenClaw Skill
Name: vx-usage
Version: 1.0.4
The skill bundle provides documentation and instructions for an AI agent to use 'vx', a universal development tool manager. It includes usage patterns for various programming languages, project configuration via vx.toml, and integrations with MCP and GitHub Actions. No malicious code, data exfiltration attempts, or harmful prompt injections were identified; the instructions are strictly focused on tool management and environment setup (referencing the legitimate repository ghcr.io/loonghao/vx).
Capability Assessment
Purpose & Capability
The name/description match the SKILL.md content: it teaches how to use vx. The skill declares no binaries, env vars, or installs, which is reasonable for an instruction-only usage guide.
Instruction Scope
The SKILL.md stays within the scope of teaching vx commands and project configuration. It does not instruct the agent to read unrelated files or to exfiltrate data. It documents that vx can inject environment variables into subprocesses (e.g., MSVC vars), which is a behavior of vx rather than an instruction to access unrelated secrets.
Install Mechanism
No install spec and no code files—this is instruction-only, so nothing is written to disk by the skill itself.
Credentials
The skill requests no credentials or config paths. It does reference environment variables (VCINSTALLDIR, VX_MSVC_ROOT, etc.) as explanatory examples; the skill does not require them. Users should note that running vx in their environment may cause vx itself to inject environment variables into subprocesses.
Persistence & Privilege
always is false and the skill is user-invocable with normal autonomous invocation allowed by the platform. There is no install or self-modification behavior requested by the skill.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install vx-usage - After installation, invoke the skill by name or use
/vx-usage - Provide required inputs per the skill's parameter spec and get structured output
